This is a Conn Wonder Improved and Wonder Perfected-Elkhart IND nickel plate bass saxophone, manufactured in 1910 with the serial number 18547. This is one of the earliest that we've seen in decent condition and a rare find with the union stamp on back. This bass might not be the prettiest looking horn but considering it is over 100 years old, it is in great shape. The original bow cap is in good shape as is the lower bow. Its body tube, bell and bell flare are also in very decent condition. The pictures do tell the story of this horn the best.
